- the isolator assembly 8 includes an isolator 10 and a hanger 31 .
- the isolator 10 includes a bracket 20 and a cushion 40 embedded in the bracket 20 .
- a connection portion 32 of the hanger 31 may be used to attach the hanger 31 to the isolator 10 .
- the bracket 20 may be connected to an underbody of the vehicle via with any appropriate approaches such as screw connection or rivet connection.

- FIGS. 3, 4, 5, and 6 are perspective views of the isolator assembly or the isolator in FIG. 2 from different angles.
- the bracket 20 includes a first arm 21 and a second arm 22 pivotably connected.
- the first and second arms 21 , 22 may have similar structures.
- the first and second arms 21 , 22 may include a first end 23 a , 23 b , respectively which are pivotably connected via a pivot 29 and a second end 24 a , 24 b , respective which are detachably connected via a locking device 25 .
- the locking device 25 may include a first locking portion 25 a disposed on the first arm 21 , and a second locking portion 25 b disposed on the second arm 22 .
- the first and second arms 21 , 22 of bracket 20 with the detachable structure can be opened during the assembling process to place the cushion 40 in the bracket 20 and then connected by the locking device 25 such that the cushion 40 is embedded in the bracket 20 .
- Each or the first and second arms 21 , 22 may have a semi-circular shape to form an annular shape corresponding to an outer perimeter of the cushion 40 . That is the bracket 20 may be a ring-shaped bracket.
- the first and second arms 21 , 22 may have a U shaped or a semi-circular shaped cross section or any shapes corresponding to the outer surface of the cushion 40 such that the cushion 40 can match an outer surface of the cushion 40 better and be firmly embedded in the two arms.

- the bracket 20 may be installed on the underbody of the vehicle via screws or rivet passing through the first and second holes 27 a , 27 b or other appropriate approaches.
- the bracket 20 may be made from rigid material like stainless steel, cast iron, alloy, or hard plastic. Comparing to the isolators of the exhaust system made entirely from elastic material, a rigid bracket can provide firm support to an exhaust system connected on the vehicle underbody, and a rigid bracket is not easy to age compared to the rubber.
- the gas filled cushion 40 may include at least a through hole 41 formed at middle portion of the cushion 40 to receive the hanger 31 connected to the exhaust pipe. That is, the cushion 40 may have an annular ring shape. Alternatively, the cushion 40 may include a plurality of through holes to adapt to the different hangers of exhaust systems. In some embodiments, the cushion 40 may include one hermitically sealed cavity 42 surrounding the through hole 41 . Gas is hermitically sealed in cavity 42 and the cushion 40 has a structure like a ring-shaped flotation device or a tire. The cushion 40 may be filed with gas with predetermined pressure. Compared to the isolator made all from solid elastic material or mostly made from solid elastic material, the cushion 40 has a hollow body and less material is used.
- the isolator 10 saves the cost. Since the cushion 40 has a hermetically sealed cavity, the cushion 40 has better elasticity to isolate vibration than an isolate made from a solid part. In addition, the through hole 41 of the cushion 40 provides a greater contact area with the hanger of the exhaust system. The vibration from the exhaust system is absorbed first by touching the surface and then absorbed further by the entire cushion 40 , and thus isolation from the vibration from the exhaust system can be improved.
- the cushion 40 may have an annular shape having a first main surface 43 and a second main surface 44 opposite to and substantially parallel to the first main surface 43 , an inner surface 45 and an outer surface 50 .

- the wall 45 of through hole 41 includes a plurality of first projections 46 adjacent to the first main surface 43 of the cushion and distributing along a circumference of the through hole 41 and a plurality of second projections 47 adjacent to the second main surface 44 and distributing along the circumference of the through hole 41 .
- the cushion 40 may further include a valve 48 connected to the sealed cavity 42 of the cushion 40 .
- the valve 48 may be positioned at any appropriate place on the surface of the cushion 40 . In the embodiment depicted in FIGS. 2 and 6 , the valve 48 is located a place adjacent to the pivot 29 of the bracket 20 . The valve 48 may pass through the bracket 20 .
- the cavity 42 may be filled with gas before or after installation of the cushion 40 via the valve 48 .
- the gas may be air, nitrogen, other inert gas.
- the valve 48 may further be used to adjust a gas pressure in the cushion 40 such that the isolator 10 may be configured to have different stiffness to meet rigidness requirement for the different vehicles. In other words, the isolator can have one configuration but the parameters for the isolation requirement may be adjusted by the gas pressure in the cushion for different types of the vehicles. Thus, the isolator can be versatile in its application.
- FIG. 7 is a cross-sectional view of the isolate 10 in FIG. 2 , illustrating connection of a hanger 31 with the cushion 40 .
- the bracket 20 is not shown in FIG. 7 .
- the hanger 31 is used to connect the exhaust system 1 to the underbody 2 of the vehicle and suspend the exhaust system 1 under the vehicle underbody 2 via the isolator 10 .
- the hanger 31 may be integrated formed with the exhaust pipe 3 of the exhaust system 1 or may be detachably connected to the exhaust system 1 .
- the hanger 31 includes a connection portion 32 that may be placed in the through hole 41 of the cushion 40 and has varied cross sectional areas.
- connection portion 32 has a first region 33 adjacent to the plurality of first projections 46 and the plurality of second projections 47 of the cushion 40 and a second region 34 between the first projections 46 and second projections 47 of the cushion 40 .
- the first region 33 has a cross section area greater than that of the second region 34 .
- the connection part 32 with varied cross-section areas can match better with the structure of the through hole 41 .
- the inner surface 45 may extend toward a center axis and have an arc shape because the inner wall of the through hole is not a cylinder with a uniform circular cross section area and the cavity is filled pressure gas.
- the first projections 46 and the second projections 47 positioned at the edge of the through hole 41 may be configured to have an interference fit with the first region 33 and the second region 34 of the inner surface of the cushion 40 .
- the interference may be in a range of about 0.1 mm to about 0.5 mm.
- Such configuration can further prevent the connecting part 32 from be disengaged from the through hole 41 .
- the hanger 31 and the cushion 40 have a large contact area.
- an outer profile of the connection portion 32 may be configured to match the profile of the through hole 41 and the profile of the first projections 46 and the second the projections 47 formed on the cushion 40 .
- FIG. 8 shows a portion of a cushion of an isolator for an exhaust system according to another embodiment of the present disclosure.
- the cushion 400 includes a plurality of sealed cavities 421 , 422 , 423 , and 425 distributed along a circumference of a through hole 41 410 , which are formed by separating walls 424 disposed on the cross-sections of the cushion 400 .
- Cavities 421 , 422 , 423 , 425 may have same or different sizes, and may be filled with gas having same or different pressure.
- Each cavity may include an independent pressure adjustment device 427 .
- the pressure adjustment device 427 may be a valve, or a protrusion or a weakened area made from an elastic material and may be positioned at the cushion. By opening the valve, or cutting the protrusion or the weakened area, the sealing of the cavity is removed to release the gas.
- the rigidness of the cushion 400 in the isolator can be adjusted by removing the sealing in one or more cavities to meet requirements of different types of the vehicle.
- Such design can avoid a process of filling/releasing gas to adjust pressure in the cushion 400 on site, but still enables the adjustment on a rigidness of the cushion 400 , therefore, and thus further enhances versatility.
- the isolator of the present disclosure comprises a gas filled cushion, which save material and improve the isolation to the vibration.
- the direction connection of the through hole of the gas filled cushion with the hanger increase the contact area such that the vibration can be absorbed effectively and the relative movement between the isolator and the hanger is reduced.
- the isolator includes a valve to adjust gas pressure inside the cushion. In this way, stiffness of the isolator may be adjusted by the valve to meet the requirement for specific type of vehicles.
- the isolator of the present disclosure is versatile and can fits different types of vehicles.
- the isolator can be used in a research and development stage of an engine and an exhaust system to determine the optimal stiffness. Stiffness of the isolator can also be changed by using different type of gas.
- the bracket with pivotal connection can facilitate assembling and disassembling of the isolator to the exhaust system, which enhance the efficiency.
